FUEL FEEDER AND DIVSTRIBUTER.

SPECIFICATION forming part of LettersIPatent N o. 567,190, datedSeptember 8, 1896.

Application filed May 28, 1894. Serial No. 512,75 7. (No model To allwhom t may concern.-

Beit known that I, LUTHER MYERS, of Maumee, county of Lucas, and Stateof Ohio, have invented certain new and useful Improvements in FuelFeeders and Distributers and I do hereby declare that the following is afull, clear, and exact description of the invention, which will enableothers skilled in the art to which it appertains to make and.. use thesame, reference being had to the accompanying drawings, and to thefigures of reference marked thereon,which form part of thisspecification.

My invention relates to a fuel feeder and distributer for furnaces,boilers, dto., and has for its object to effect an even and continuousfeed of fuel to the grate-bars of the furnace, boiler, &c., anddistributev the same evenly over the entire surface of the grate.

The invention consists in a spout and means for giving a vibratorymotion to the same to feed the fuel, and means for giving side movementto distribute the fuel over the entire surface of the grate.

The invention further consists in the parts as shown, described, andclaimed.

Figure 1 is an elevation of a portion of the furnace provided with myinvention. Fig. 2 is a sectional elevation illustrating the means forgiving a vibratory movement to the spout. Fig. 3 is a sectional view ofthe device, taken at a point indicated by lines me, Fig. 1, illustratingthe guides for the spout in the revolving hopper. Fig. 4 is asectionalelevation taken at a point indicated by lines y y, Fig. 3, in furtherillustration of the guides for the spout. Fig. 5 is a plan view of therevolving hopper, showing more particularly the mechanism for revolvingthe same. Fig. 6 is a detail view of the spout, illustrating themodiiication comprising a jacket for use when it is desired to employ acooling medium to lower the temperature of the spout.

This invention has for its object economy of fuel, which isaccomplished, first, by an even feed of fuel to the grate-bars; second,by an even distribution of the fuel over the entire surface of thegrate-bars; third, by coking the fuel previous to the feed to thegrate-bars, and, fourth, by admission of the necessary quantity of airto support perfect combustion. These objects are accomplished,

rst, by a vibratory movement of the hopper, which causes an even feed ofthe fuel therein, and comprises a hopper 1, having a spout 2 extendinginto the furnace and above the grate-bars. ment along the length of thesame and slides back and forth, guided by ways or guides 3.

4 designates a shaft journaled in the bearing 5 upon the frontof thefurnace and eX- tending inside of the hopper, having a crankarm 6, therebeing an arm 7 pivotally connecting .the crank-ann and the spout at 8,whereby, when the shaft 4 is revolved, the crank is caused to revolveand through the medium of the arm 8 vibrating the spouty backward andforward, the fuel having an even feed into the spout through the opening9 in the hopper, and to cause an even feed to the hopper I provide aCrusher 10, driven by any suitable source of power, there being aconveyer 1l .to convey the fuel from the crusher into the opening 9 tothe spout. The quantity to feed to the spout is regulated by themovement of the conveyer.

In order to distribute the fuel as it issues from the opening 9 in thespout over the en, tire surface of the grate, the hopper 1 revolves backand forth, carrying the spout therewith. Therefore the movement of thespout is over the entire surface of the grate. The mechanism forrevolving the hopper comprises a pinion 13 upon shaft 4, which mesheswith and revolves a pinion 14 upon a shaft 15, journaled in a bearing16, secured to the front of the furnace, and upon said shaft 15 there isa pinion 17, which in turn meshes with and revolves a gear-wheel 1S.Upon the upper surface of the gear-wheel 1S are a plurality ofupwardly-projecting arms 19,which revolve in the path of travel of thearm 20, secured to the hopper. Therefore, as the shaft 4 revolves,gear-wheel18 will be revolved through the medium of pinions 13, 14, and17, and the upwardly-projecting arms 19, as theyrevolve, will carry thearm 2O therewith, which is bent down, as shown in Figs. 1 and 2, andAsecured to the edge of the hopper, and consequently carry the hopper,until released by reason of the arm 19 revolving away from arm 20, inwhich event the arm 2O is released, when spring 21 will revolve thehopper back to its original position, or until the arm 2O strikes Thespout has a vibratory move- IOO products of combustion, obviating thesmoke,

and by reason of the draft through the spout air is drawn therethrough,Which mixes with the unconsuming products at a point above thegrate-bars, adding the necessary air to support combustion of the same.

By reasonof the intense heat towhich the spout `may be subjected, ifdesired, I may jacket `the spout, forming a Water-space 22, p

which will serve to keep the temperature of the spout down to a degreeto prevent the same from melting.

In operation fuel is fed into the hopper of the crusher and the crusherand feeding mechanism are started. The Crusher will crush the fuel as itpasses therethrough into the desired size, the conveyer carrying it tothe spout. The spout of the crusher and conveyer being regulated willdetermine the amount-of fuel to be fed into the furnace.

While I have shown the vibratory spout havingside motion the Width ofthe grate, I wish it understood that I may vary this feature broadly.As,for instance, the spout may have a vibratory side motion or move inand out, the operation being the same.

Vhat I claim is- 1. In a fuel feeder and distributer, a furnace, a gratetherein, a spout and means for mechanically carrying the fuel thereto,and means for moving the spout sidewise above the grate.

2. Ina fuel feeder and distributeiga furnace provided with a grate, aspout and means for mechanically carrying the fuel thereto,

and mechanism for vibrating and giving side mov-ement to the spout abovethe grate.

3. In a fuel feeder and distributer, a furnace provided With a grate, aCrusher, a spout having mechanism for vibrating the same above the grate, and an endless conveyer connecting the crusher and the spout.

4. In a fuel feeder and distributer, a furnace provided With a grate, arevoluble hopper and means for revolving the same, a spout carriedthereby and revoluble therewith, and means for vibrating the spoutindependently of the movement of the hopper, the inner end Of the spoutextending Within the furnace above the grate.

5. In a fuel feeder and distributer, a furnace provided with a grate, arevoluble hopper secured to the furnace,.a spout Vcarried thereby, ashaft and means for revolving the same, a crank located upon the lowerend of `the shaft, and a link connecting the crank and the spout.

6. In a fuel Vfeeder and distributer, a furnace provided with a grate, ahopper secured to the furnace exteriorly of the same, a spout carriedthereby, mechanism for revolving the hopper in one direction, and meansfor automatically releasing the said mechanism and returning the hopperto its original position.

7 In a fuel feeder and distributer, a furnace provided With a grate, arevoluble hopper secured thereto,.a spout carried thereby having achamber for cooling medium surrounding the same, the inner end of thespout extending into the furnace and above the grate.

In testimony that I claim the foregoing as my own I hereby affix mysignature in presence of two Witnesses.

LUTHER MYERS.
